Ronian's latest paper has been published in the European Journal of Physics! In this new work, Ronian extends conventional optical radiometry to the case of non-stigmatic, non-aplanatic, and non-isoplanatic lenses. In other words, you can now apply the image "brightness" calculations from radiometry to any lens, such as commercial off-the-shelf lenses forming the image of any source onto a sensor.

Wrapping up the year in 2020, Ronian publishes a technical note describing how to apply a simple formula to compute the relative illumination of an un-vignetted imaging lens system in terms of image distortion, differential distortion, chief ray angle (in object space), and the size and shape of the entrance pupil.
